Application lled November l1908. Serial-No. 460,589.

.W ellwhmit Mygfconoemf" form ofsquare,ftriangular,.or any other de- Be it known that .I ,onN C. KINGSBURY, a citizen 'of the United States, residing at Y Haey, Iin the co "of Worcester and sired cross section, as the shape ofthe pieces 1s not important. In order to make them, the' packingsnow ordinarily employed'.

v first three figures; and Fig. 5 is asimilar? Vis a View. showing a form of packing suifta 'i tight ,`j"oint, gl have 'provided' a for-medias follows-Tlteference first 1s telco" [hadito 'Eig'. 4in which apacking lmaterlal if,

Stateof Nlassachltts 4have invented a new and useful racking, 0l which the renewing Lllhiszinventi' n able for use for steam or 'hot-water, and in better than the ormnowlimnsegrwhich' will be cheaper to make and easier to apply;

and which after a small amount of'wear willi,

not-become iiseless as, is the case vwith ythe;V

llteferenceis to befli'ad tothe arc'ompany.-4 in drawings, in which-v igare l` `s'a,s e ctional view of' as tullng` box ;"F-ig.' 2`is a similar view of a piston lor'f cylinder; and Figfjli'is asimilar view cfa, portion of a valve, showing certain ways'li'n which the invention may be applied.;

for application 1n the devices shown i I 1f .th e a` view showing an additionalffeature..

lt has been customary to make packin j;

-in a predetermined form so that each'jpac -rf ing isinecessarily `made for the particular place n v'which it is to be appledfjand 4con-iig sequently a packing made fr-one place will ordinarily not it in another?. Another fdij advantage of these packings of a deirite';` shapeconsists in the fact that .theyare di'iicult vandexpensive to vUlt in position, and it is ofcourse` well understood that when pnl replaced,j`almost all' of the old packing thus being rendered "useless packing in position, and V Whic can' r-be pnt: iin place easily andy compressed in a con#v venlent'way to the desired extent so to',v

secure the" necessaryI pressure' for a steamepacking;

- 1 shown' as cnt up into, small bloc s,'preferA-' -ab'lyof angular 'oir-poly onal form, 'but' which-may conveniently e made 4of -ir: regular shapes. 'I hey maybe made '1n the l'relates-to a packing suiti 'fca'n be ',obtained' than wlth th packing material, as .zfor exangle, rubber, frictioned-duck, combinations o elastic maf terial with canvas and other textile materials, and even gatta-perche, leather, or any other .material which can be used for the 'particular pur ose, are putthrough a machme or cut 65 allaces where packings are ordinarily? tip y hand 1nto small pieces @preferably L- from one-quarter to one-half of an nach wide,

.longand. thick. These-'pieces may, if dejsired, be mixed with mallparticles of as-- bestos b as shown inlligi, or they may bel l, d in Fig. 2,?ore in Fig. 3,is'exposed :1n any ordmary way, and the packing :ip-'.75

plied by hand and crowded down into the cavity5-after which aca gland, or the like,

`fis Iappliedand the pac ing compressed by .forcing the same'int'o, position, or in case of a piston the packing 1s referably pressed 80 into the .grooves by'han and when it is 'fully compressed, the piston is movedback intothewc linder.

I "have :tound'in ract'ice that by the use of apackingofthis o rm,"a much t1 ordinary forms of' packing, and that it will hold longer, and ,when it does getworn, more .pressnrecan bmaPplied', in the form shown the packing' tighten up again; also that .when -itfi'srnecessary to' renew ,the packing, this can-befdone'simply by adding a portion jof new material without. removing theold,

Ipas that the entire packing is consumed 95 -slightlyfwoi'n they have to be removed andi'.

eventually and none of Ait has to be taken 'jaway and discarded. l'n vthis way great economy vis'introduce'd, land moreover small particles or scraps of acking can/'bel used.

:without losing any va liable propertiesoffiioo the packing. t i, The particles of packing/"preferably are covered 'o r coated with graphite' before "being put imposition. Also in Acases where- V'the parts of the device4 to be packed-aresofiip 4'worn that it is hard toretainan 'z'ordinaryf ackingfin proper; positi'om'these pieces cany be used alone bit they can bekept -i n better by' p lac'ing' some jpi'eces of Babbitt; `or. otherv bear'mgmetal -around the worn part to sns-$1510' tain thepackngj. 'Ifhese metal pieces or shot' preferably 'aref-aade spherical, or at leastr ter joint 8 5 or example, so asto make they have smooth edges, as shown at f in and unconnected blocks of soft ru in by any plerson skilled in the art without Y departingi om the scope of the invention as expressed :in the claims. Therefore I do not wish to be limited to all the details of construction shown, or to plications illustrated, but What I do claim 1s:-

1. A' packing consisting of a iplurality of.-

individual, independent, and eely se a'- rable blocks of packing material of irregular shape Yfilling the entirespace to be acked and in direct Contact with the walls t ereof.

2. A packin comprisin a lurality of homogeneous, eely separale, P

mderendent ber of su'ch shape and size as to be capable of being han ed individually.

4. A packing consisting of a luralit o'f independent and unconnected b ocks o resilient packing material mixed with asbestos free from binding materials and held in position under pressure.

5. A acking consisting cf a pluralitty of indepen ent-and unconnected blocks o resilient packing material mixed with asbestos coated with graphite.

In testimon whereof I have hereunto set my hand, in t witnesses.
